SPECIFICATION forming part of Letters Patent No. 303,330, dated November 13, 1384.

Application filed May 15, 185-4.

To (LZZ whom if; may concern..-

Be it known that I, FREDERICK Srnonnr, a citizen of the United States, and a resident of Marion, in the county of Marion and State of Ohio, have invented certain new and useful Improvements in Olover-Hullers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art'to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in *which Figure 1 is a longitudinal vertical sectional view of my improved clover-huller; and Fig. 2 is a top or plan view of the same, showing parts of the frame or outer casing broken away, the better to illustrate the construction of the various parts. I

' Similar letters of reference indicate corresponding parts in both the figures.

My invention consists in the improved construction and combination of parts of a cloverhulling machine, as will be hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying drawings, A represents the frame or outer casing of my improved machine. This frame or casing is provided at its upper and forward end with an inclined feed-board or table, down which the cloverheads are fed so as to pass beneath the thrashing-cylinder B and over the beater 0, both of which are of ordinary construction.

In the upper portion of the frame A, immediately behind the beater (J, are supported the racks DE, the upper rack, D, the spaces between the slats of which are greater than those of the lower rack, E, being placed at such a height as to receive the coarse material thrown from the cylinder B and beater C.

These two racks are both supported upon the double cranks F of the three shafts, F F F, the central shaft being provided at one end with a band-wheel, G, to which the power is applied by means of an endless belt from any suitable source of power, while the opposite end of the shaft and the corresponding ends of the two end shafts are each provided with a small wheel, G, having a wrist-pin, F, for the attachment of a pit-man, G, the said wrist-pins No model.)

being placed at such a distance from the center of the wheels G that the revolutions of the band-wheel G will reciprocate the two IEHkS in the position shown in dotted lines in' Fig.

stices of the finer rack Eupon a solid bottom, H, extending from the rear part of the frame A to a point immediately over the hullingcylinder I, this solid bottom being placed at such a distance below the lower rack, E, that the said rack will at each of its downward re ciproeating motions, feed the seed down the bottom H, which is slightly inclined, into the hnllingcylinder I. The seeds and rubbish are thrown out of the hulling-cylinder upon the bottom M, and are sifted upon the perforated portion 0 of the same, the seed and finer rubbish or refuse matter falling through upon the riddles N N, where, by aid of the blast from the fan P,the seeds are thoroughly cleaned fromthe chaff and drop through upon the bottom 12-, which works the seed rearward to the opening immediately in front of the blastboard 1 which opens upon an inclined board, T, leading to the delivery-chute U, a screen, S, being secured a little above the board T, and extending across the mouth of the chute U, the seed working through this screen while the refuse matter, still mingled with the seed, will fall over the lower end of the screen upon the ground or floor. The refuse matter falling from the rear end of the bottom M and riddles N N is received in the tailings-spout Y 1nd is carried up by the elevator IV to a point near the middle of the machine, directly over the hulling-cylinder, into which it is discharged. That portion of the bottom M which extends above the drum of the fan P is made solid. The lower rack, E,'is provided at a ing, and the forward end of the said rack, which is made solid, is extended beneath the beater C, so as to receive any matter which fails to pass over and above the said heater and then feeds it rearwardly into the hullingcylinder.

The various shafts may be run by any suitable system of gearing, which I do not deem it necessary to specify, as any desired form may be employed.

. From the foregoing description, taken in connection with the accompanying drawings, the construction and operation ofmyimproved hulling-machine for clover will be readily understood without requiring further explanation. It will be seen that by the use of the double racks the separating of the seed from the refuse matter will be most thoroughly ac complished.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. As an improvement in clovcr-hulling machines, the combination, with the thrashing mechanism, the beater, the hulling mechanism, and the solid inclined bottom II, of the double racks D and E, supported upon and reciprocated by thedouble cranked shafts F F F, the interstices of the upper rack being 30 larger than those of the lower'one, and the lower rack being provided with an opening immediately over the balling-cylinder, and having its forward end made solid and extended beneath the beater, whereby any matter passing from the thrashing mechanism and failing to pass over the beater will be caught by the forward solid end of the lower rack and fed down into the hulling-cylinder, as and for the purpose shown and set forth.

2. As an improvement in clover-hulling machines, the combination, with the thrashing mechanism, the beater, the hulling mechanism, and the double racks D and E, constructed and operated as described, of the solid inclined bottom H, extending from the rear part of frame A to apoint immediately above the hulling-cylinder I, and secured in the frame A at such a distance beneath the lower rack, E, that the seed and light refuse matter falling through the interstices of the said rack upon the said solid bottom will be fed down into the hulling-cylinder by the downward reciprocating movements of the said lower rack, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signa ture in presence of two witnesses.

FREDERICK STROBEL.
